This invention relates to! a support for a hinged or plvotally mounted auto-moblle seat, suchias used in coachesor sedans, the general object 'ofzthe invention being to provide a featuresof construction and inthe combi-" nation and arrangement of the several parts,

to be hereinafter fully described, illustrated in the accompanying drawings and specificauy pointedout in the appended claims.

In describingthe-invention indetail, reference will be had. to-the 'accompanying draw- :5 ings whereinlikecharactersdenotelike or corresponding parts throughout-"the several views, and 1n Wlnchz- 1 Figure 1 is ,a view showingthe invention in use. 1 r

Figure 2 is a section on line 2-2 of Figure 1. i r

perspective view of the seat view of the spring.

Figure 6 is a View of'one of the'fioor plates Figure 7 is a View of theotherfioor plate; Figure 8 is a rearpviewshowing thein- Y ventionplaced sidewise of the seat instead Qoif lengthwise, as in Figure 1.: r l As shown in these views, the device includes a .seatjengaging member 1v and'a semi-elliptical spring 2. The'member 1 carriese bolt 3, the head of whichis countersunk in the holds the bolt to the member 1. The bolt passes throughria'hole 5rformediin the spring to one side o'fthe centerof the length of the springend a circular nut 6 on the bolt engages the under face oft-he spring. A hand sprin top of the member 1 and a nut 4 on thebolt wheel 7, having a centrallvarranged threaded aperture thereinior receiving the bolt, 1s located betweenthe spring and themember 1 so that by'turning this wheel in one direction or tl1e'other,:the members 1 and-2 can" be ed3usted relatlve to-each other. The meIn-' V ber 1 isprovided with ,a turned-up end 1-,

and this member is placed under the seat,' as shown in Figure 1, with ltS turned-up end engaging the rear part of the seat so that the member is prevented from sliding on the seat. The spring 2 may-extend lengthwise of the seat, as shown in Figure 1, or sidewise thereof, asshownin Figure. 8. As shown in Figure 1 the long part of the spring should extend towardthe front and when the spring isuscd; as inQFig'ure 8, the longpart of the g should extend toward the second seat. Shoes orfloor piates Send 9 are provided for the ends otthe spring, each plate being of channel shape, with thefianges at the sides ech platecut and bentinto horizontal pos.

tion, with the outer corners of the plates bent ,(lowiiwardly to form points 10 so th'at these points will engage thefioor of the vehicle and thus prevent-the shoes or plates fromslipping. f The rear plate 8' is formed" with an upstanding flange -11 atfitsrearend 'against which the rear end of the spring will abutand thus this end of the spring is'held s ring is rounded, as shown at 2", so that this endslidingly engagesthe front plate 9 and can movethereon. The plates are arranged with their poi'nts'at the rear when thedevice i is used, as shown in Figure l. Asshown in Figure'8, the plates are so placed that the shot-term engages the'flange'd plate Send the long; arm engages.theplateQ, thepointed ends offt-ne plates f tron, asshowngq a-cing in the same direcvagainst movement. The other end of the As shown in Figures-Land 8, the device should'be so adjusted thatthe rear legs of the the rear-portionot the seat is supported by the spring end thusi the'spring will act to absorb shocksand Jars and makecomfortable P riding for'the occupant of the seat; There s is no rebound to the spring as the weight of I the seat aiidth'e occupantis carried at an seat are heldofi the floor the device, so that i 40 carried by the bar and passing through the weight is oil center.

' the long arm against the seat bottom and holds it to'the seat as securely as if it we.

bolted. I

The underpartof the waeel 4 is formed with a spherical part 7 for. engaging the spring so that the member 1 can have rocking movement and the hole in the spring through which the bolt passes is large enough togive free play to the bolt. The oii center position of the weight on the spring lengthens the life of the spring andthe points on the floor plates hold theplates at an angle so that one end ofthe spring can readily slide thereon and theflangeson the plates prevent the spring from slipping off the plates. As

before stated the device not onl forms a resilient support for the seat, but makes the seat adjustable to suit the person using the seat and this adjustable feature of the device makes it capable of use with different kinds and sizes of seats; 7 j 7 It is thought from the foregoing descriptionthat the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in th-e combination and arrangement of the severalparts,

provided that such changes fall within the.

scope of the appended claims.

,VVhat I claim is l 1. In combination with a hinged or pivoted seat; a bar engagingthe under side of the seat, asemi-elliptical spring having a hole therein to one side of the center, a bolt hole, a hand wheel having a threaded aperture through which the bolt passes, said hand wheel being arranged between the bar and the spring whereby the space between the bar and springcan be adjusted.

2. In combination with a hanged or pivoted seat, a bar engaging the under side of the seat and having a bent-up rear end for engaging a portion ofthe rear of the seat, a semi-elliptical spring having a hole therein'to one side of the center, a bolt carried by the bar and passing through the hole, a'hand wheel having a threaded aperture through which the boltpasses, said hand wheel being arranged between the bar and the spring whereby the-space between the bar and spring can be" adjusted, said handwheel having a. spherical lower portion for engaging the spring.

, 3. In combination with a hinged or pivoted I seat, a bar engaging the under side of the seat and having a bent-up rear end for engagmg a portion ofthe rear of the seat, a seml-elllp- .tical spring havinga hole therein to one side lower portion for engaging. the spring and a pair of channel-shaped floor plates for receiving the ends of the spring, each plate having depending points at one end thereof and one of the plates having an upturned flange for engaging one end of the spring.

4t. In combination with a hinged or pivoted seat, a bar engaging the under side of the seat and having a bent-up rear end for engaging a portion of the rear of the seat, a semi-elliptical spring having a hole therein to one side of the center, a bolt carried by the bar and passing through the hole a hand wheel havingoathreaded aperture through which the bolt passes, said hand wheel being arranged between the bar and the spring whereby the space between the bar and spring can be adjusted, said hand wheel having a spherical lower portion for engaging the spring and a pair of channel-shaped floor plates for receiving the ends of the spring, each plate having depending points at one endthereofimd one of the plates having an upturned flange for engaging one end of the spring,'the oppositeend of the spring being rounded on its under side to engage the plate.

5. In combination with a pivoted seat, a

bar engaging the under side of the seat, a

spring swivelly secured intermediate its ends to the bar and having portions which are adapted to serve as legs for the seat and means for adjusting the spring at its point of connection with the bar toward and away from said bar.

In testimony whereof I afiix my signature.
